Professional society guidelines recommend risk-reducing salpingo-oophorectomy (RRSO) for women with pathogenic variants (PVs) in ovarian cancer-risk genes. Personalization of that intervention is based on gene-specific phenotypes; however, the age of ovarian cancer diagnosis in women with PVs in moderate penetrance ovarian cancer-risk genes is not well characterized. Women who had hereditary cancer panel testing from September 2013-May 2019 were included (N=?631,950). Clinical/demographic information was compared for women with a PV in BRIP1, RAD51C, or RAD51D versus in BRCA1 or BRCA2.
PVs in BRIP1, RAD51C, or RAD51D were identified in 0.5% of all tested women but in 1.6% of women with a history of ovarian cancer (~?3-fold increase). PVs in BRCA1 or BRCA2 were identified in 2.4% of all tested women but in 6.1% of women with a history of ovarian cancer (~?2.5-fold increase). The proportion of women with a personal or family history of ovarian cancer was similar among women with a PV in BRIP1, RAD51C, RAD51D, BRCA1, or BRCA2. The median age at ovarian cancer diagnosis was 53?years for BRCA1, 59?years for BRCA2, 65?years for BRIP1, 62?years for RAD51C, and 57?years for RAD51D.
These data reinforce the importance of identifying PVs in moderate penetrance ovarian cancer-risk genes. The age at ovarian cancer diagnosis was older for women with PVs in BRIP1, RAD51C, or RAD51D, suggesting that it is safe to delay RRSO until age 45-50 in RAD51D PV carriers and possibly until age 50-55 in BRIP and RAD51C PV carriers.

From December 2016 to April 2020, 8 patients with giant cell tumor of bone in the proximal tibia underwent intralesional curettage of the tumor and reconstruction with bone grafting and three-dimensional-printed porous implant. Detailed anatomy data were measured, including the size of lesion and thickness of the subchondral bone. Prostheses were custom-made for each patient by our team. All patients were evaluated regularly and short-term clinical outcomes were recorded.
The mean follow-up period was 26 months. According to the different defect sizes, the mean size of the plate and mean length of strut were 35 × 35 mm and 20 mm, respectively. The mean affected subchondral bone percentage was 31.5%. The average preoperative and postoperative thickness of the subchondral bone was 2.1 mm and 11.1 mm, respectively. There was no wound infection, skin necrosis, peroneal nerve injury, or other surgical related complications. No degeneration of the knee joint was found. https://www.selleckchem.com/products/PP242.html Osseointegration was observed in all patients. The MSTS improved from an average of 12 preoperatively to 28 postoperatively.
The application of three-dimensional-printed printed porous prosthesis combined autograft could supply enough mechanical support and enhance bone ingrowth. The design and operation management lead to satisfactory subchondral bone reconstruction.

Observation and analysis of various morphological phenotypic traits during maize growth are essential for genetic and breeding study. The generally huge number of samples produce an enormous amount of high-resolution image data. While high throughput plant phenotyping platforms are increasingly used in maize breeding trials, there is a reasonable need for software tools that can automatically identify visual phenotypic features of maize plants and implement batch processing on image datasets.
On the boundary between computer vision and plant science, we utilize advanced deep learning methods based on convolutional neural networks to empower the workflow of maize phenotyping analysis. This paper presents Maize-IAS (Maize Image Analysis Software), an integrated application supporting one-click analysis of maize phenotype, embedding multiple ant science.
The Maize-IAS is easy-to-use and demands neither professional knowledge of computer vision nor deep learning. All functions for batch processing are incorporated, enabling automated and labor-reduced tasks of recording, measurement and quantitative analysis of maize growth traits on a large dataset. We prove the efficiency and potential capability of our techniques and software to image-based plant research, which also demonstrates the feasibility and capability of AI technology implemented in agriculture and plant science.Drug-resistant falciparum malaria is an increasing public health burden. This study examined the magnitude of Plasmodium falciparum infection and the patterns and predictors of treatment failure in Vietnam.
Medical records of all 443 patients with malaria infection admitted to the Hospital for Tropical Diseases between January 2015 and December 2018 were used to extract information on demographics, risk factors, symptoms, laboratory tests, treatment, and outcome.
More than half (59.8%, 265/443, CI 55.1-64.4%) of patients acquired Plasmodium falciparum infection of whom 21.9% (58/265, CI 17.1-27.4%) had severe malaria, while 7.2% (19/265, CI 4.6-10.9%) and 19.2% (51/265, CI 14.7-24.5%) developed early treatment failure (ETF) and late treatment failure (LTF) respectively. Among 58 patients with severe malaria, 14 (24.1%) acquired infection in regions where artemisinin resistance has been documented including Binh Phuoc (11 patients), Dak Nong (2 patients) and Gia Lai (1 patient). Under treatment with intravenous artesunate, the median (IQR) parasite half-life of 11 patients coming from Binh Phuoc was 3h (2.
